(protruding nails or sharp edges) and chemical (harmful fluids or dust) hazards posed by wastes.
In addition, illegal dumping can impact proper drainage of runoff, making areas more susceptible to flooding when wastes block ravines, creeks, culverts, and
drainage basing. Runoff from dump sites containing chemicals may contaminate wells and surface water used as resources of drinking water. Countless neighborhoods have been evacuated and property damage has been significant because of dump sites that caught fire, either by spontaneous combustion or, more commonly, by arson.
If not addressed, illegal dumps often attract more waste, potentially including hazardous wastes such
as asbestos, household chemicals and paints, automotive fluids, and commercial or industrial wastes.
